NAME

6       mount_ecryptfs_selinux   -  Security  Enhanced  Linux  Policy  for  the
7       mount_ecryptfs processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the mount_ecryptfs processes via flexi‐
11       ble mandatory access control.
12
13       The  mount_ecryptfs processes execute with the mount_ecryptfs_t SELinux
14       type. You can check if you have these processes  running  by  executing
15       the ps command with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep mount_ecryptfs_t
20
21
22

ENTRYPOINTS

24       The   mount_ecryptfs_t   SELinux   type   can   be   entered   via  the
25       mount_ecryptfs_exec_t file type.
26
27       The default entrypoint paths for the mount_ecryptfs_t  domain  are  the
28       following:
29
30       /usr/sbin/mount.ecryptfs,                    /usr/sbin/umount.ecryptfs,
31       /usr/sbin/mount.ecryptfs_private, /usr/sbin/umount.ecryptfs_private
32

PROCESS TYPES

34       SELinux defines process types (domains) for each process running on the
35       system
36
37       You can see the context of a process using the -Z option to ps
38
39       Policy  governs  the  access confined processes have to files.  SELinux
40       mount_ecryptfs policy is very flexible allowing users  to  setup  their
41       mount_ecryptfs processes in as secure a method as possible.
42
43       The following process types are defined for mount_ecryptfs:
44
45       mount_ecryptfs_t
46
47       Note:  semanage  permissive -a mount_ecryptfs_t can be used to make the
48       process type mount_ecryptfs_t permissive. SELinux does not deny  access
49       to permissive process types, but the AVC (SELinux denials) messages are
50       still generated.
51
52

BOOLEANS

54       SELinux  policy  is  customizable  based  on  least  access   required.
55       mount_ecryptfs  policy  is  extremely flexible and has several booleans
56       that allow you to manipulate the policy and run mount_ecryptfs with the
57       tightest access possible.
58
59
60
61       If you want to allow users to resolve user passwd entries directly from
62       ldap rather then using a sssd server, you  must  turn  on  the  authlo‐
63       gin_nsswitch_use_ldap boolean. Disabled by default.
64
65       setsebool -P authlogin_nsswitch_use_ldap 1
66
67
68
69       If  you  want  to deny any process from ptracing or debugging any other
70       processes, you  must  turn  on  the  deny_ptrace  boolean.  Enabled  by
71       default.
72
73       setsebool -P deny_ptrace 1
74
75
76
77       If  you  want  to  allow  any  process  to mmap any file on system with
78       attribute file_type, you must turn on the  domain_can_mmap_files  bool‐
79       ean. Enabled by default.
80
81       setsebool -P domain_can_mmap_files 1
82
83
84
85       If  you want to allow all domains write to kmsg_device, while kernel is
86       executed with systemd.log_target=kmsg parameter, you must turn  on  the
87       domain_can_write_kmsg boolean. Disabled by default.
88
89       setsebool -P domain_can_write_kmsg 1
90
91
92
93       If you want to allow all domains to use other domains file descriptors,
94       you must turn on the domain_fd_use boolean. Enabled by default.
95
96       setsebool -P domain_fd_use 1
97
98
99
100       If you want to allow all domains to have the kernel load  modules,  you
101       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
102       default.
103
104       setsebool -P domain_kernel_load_modules 1
105
106

124
125       setsebool -P kerberos_enabled 1

MANAGED FILES

144       The SELinux process type mount_ecryptfs_t can manage files labeled with
145       the following file types.  The paths listed are the default  paths  for
146       these  file  types.  Note the processes UID still need to have DAC per‐
147       missions.
148
149       mount_ecryptfs_tmpfs_t
150
151
152       pam_var_console_t
153
154            /var/run/console(/.*)?
155
156       user_tmp_t
157
158            /dev/shm/mono.*
159            /var/run/user(/.*)?
160            /tmp/.X11-unix(/.*)?
161            /tmp/.ICE-unix(/.*)?
162            /dev/shm/pulse-shm.*
163            /tmp/.X0-lock
164            /tmp/hsperfdata_root
165            /var/tmp/hsperfdata_root
166            /home/[^/]+/tmp
167            /home/[^/]+/.tmp
168            /tmp/gconfd-[^/]+

FILE CONTEXTS

172       SELinux requires files to have an extended attribute to define the file
173       type.
174
175       You can see the context of a file using the -Z option to ls
176
177       Policy  governs  the  access  confined  processes  have to these files.
178       SELinux mount_ecryptfs policy is very flexible allowing users to  setup
179       their mount_ecryptfs processes in as secure a method as possible.
180
181       STANDARD FILE CONTEXT
182
183       SELinux  defines  the file context types for the mount_ecryptfs, if you
184       wanted to store files with these types in a diffent paths, you need  to
185       execute  the  semanage  command to sepecify alternate labeling and then
186       use restorecon to put the labels on disk.
187
188       semanage       fcontext       -a       -t        mount_ecryptfs_tmpfs_t
189       '/srv/mymount_ecryptfs_content(/.*)?'
190       restorecon -R -v /srv/mymount_ecryptfs_content
191
192       Note:  SELinux  often  uses  regular expressions to specify labels that
193       match multiple files.
194
195       The following file types are defined for mount_ecryptfs:
196
197
198
199       mount_ecryptfs_exec_t
200
201       - Set files with the mount_ecryptfs_exec_t type, if you want to transi‐
202       tion an executable to the mount_ecryptfs_t domain.
203
204
205       Paths:
206            /usr/sbin/mount.ecryptfs,               /usr/sbin/umount.ecryptfs,
207            /usr/sbin/mount.ecryptfs_private,   /usr/sbin/umount.ecryptfs_pri‐
208            vate
209
210
211       mount_ecryptfs_tmpfs_t
212
213       -  Set files with the mount_ecryptfs_tmpfs_t type, if you want to store
214       mount ecryptfs files on a tmpfs file system.
215
216
217
218       Note: File context can be temporarily modified with the chcon  command.
219       If  you want to permanently change the file context you need to use the
220       semanage fcontext command.  This will modify the SELinux labeling data‐
221       base.  You will need to use restorecon to apply the labels.
222
223

COMMANDS

225       semanage  fcontext  can also be used to manipulate default file context
226       mappings.
227
228       semanage permissive can also be used to manipulate  whether  or  not  a
229       process type is permissive.
230
231       semanage  module can also be used to enable/disable/install/remove pol‐
232       icy modules.
233
234       semanage boolean can also be used to manipulate the booleans
235
236
237       system-config-selinux is a GUI tool available to customize SELinux pol‐
238       icy settings.
